Imagine your kitchen as a living organism. If the stove is the heart, pumping heat and energy into your meals, then the range hood is undoubtedly the lungs.
Many homeowners treat the range hood as an afterthought—a noisy metal box above the stove that they only turn on when they burn toast. However, in modern airtight homes, it is arguably the most critical appliance for your health and home maintenance.
In this comprehensive guide, we will define exactly what a range hood is, explore the mechanics of how it protects your family from indoor pollution, and breakdown the different styles available for your dream kitchen.
The focal point of the modern kitchen: Stylish yet functional.
Phase 1: What Exactly Is a Range Hood?
A range hood (also known as a vent hood, exhaust hood, or extractor fan) is a mechanical fan enclosed in a canopy, installed directly above your stove or cooktop. Its primary purpose is to remove airborne contaminants created during the cooking process.
It performs three critical functions:
-
1. Filtration (Grease Removal):
As you cook, grease vaporizes. Without a hood, this sticky residue settles on your cabinets, walls, and ceiling, creating a yellow film that traps dust. A hood pulls this vapor through metal filters, trapping the grease before it spreads. -
2. Ventilation (Smoke & Toxin Removal):
Cooking produces smoke, steam, and dangerous gases like Carbon Monoxide (CO) and Nitrogen Dioxide (especially from gas stoves). The hood sucks these pollutants out of your breathing zone. -
3. Illumination:
Range hoods come equipped with lights to illuminate your cooking surface, making it safer to chop, sear, and sauté.
Phase 2: Ducted vs. Ductless (The Mechanics)
Not all hoods work the same way. Understanding the difference between Ducted and Ductless is the most important part of buying one.
1. Ducted Systems (Vented)
This is the gold standard. The hood is connected to a duct pipe that runs through your ceiling or wall to the outdoors. It completely expels stale air, heat, and moisture from the house.
2. Ductless Systems (Recirculating)
Used in apartments or condos where you cannot drill holes in the wall. These hoods pull air through a Charcoal (Carbon) Filter to scrub odors and then release the cleaned air back into the kitchen. Note: They cannot remove heat or humidity.
Match the Hood to Your Cooking Style
Whether you need efficient ventilation for Light-duty Cooking or professional power for Heavy-duty Cooking, we have the perfect fit.

Form follows function. The layout of your kitchen dictates which style you need.
1. Wall Mount Hoods
Installed against a wall where there are no cabinets. They feature a decorative chimney stack that hides the ductwork. The most popular choice for modern kitchens.
2. Island Hoods
Suspended from the ceiling over a kitchen island. Since they are exposed on all sides, they are finished beautifully 360 degrees and require higher power to capture cross-drafts.
3. Insert Hoods
The "hidden" power. These units fit inside a custom-built cabinet or hood cover. Perfect for traditional kitchens where you want to hide the stainless steel.
4. Under Cabinet Hoods
Compact units that mount directly underneath an upper cabinet. Ideal for saving space and for simple replacements of older units.
Phase 4: Understanding CFM and Noise Level (dB)
When shopping at Brano, you will see two numbers on every product page: CFM and Noise Level. What do they mean for your daily cooking?
CFM (Cubic Feet per Minute)
This measures power. It tells you how much air the fan can move in one minute.
Rule of Thumb: For electric stoves, you need 300-400 CFM. For gas stoves or heavy frying, you want 600-900 CFM.
Noise Level (Decibels / dB)
This measures sound. Many older hoods are so loud that people refuse to turn them on.
The Brano Standard: We believe you should be able to hold a conversation while cooking. Brano range hoods are engineered to operate at under 70dB even at high speeds, ensuring efficient ventilation without the headache.
Conclusion: An Investment in Health
A range hood is not just a kitchen accessory; it is a long-term investment in your home's air quality and cleanliness. Whether you are remodeling a chef's kitchen or updating a cozy apartment, choosing the right ventilation system is the first step toward a healthier home.
Frequently Asked Questions (FAQ)
1. What is the main purpose of a range hood?
Its main purpose is to improve indoor air quality by removing smoke, grease, odors, and heat generated during cooking, preventing them from spreading throughout your home.
2. Do I legally need a range hood?
Building codes vary by state. While not always mandatory for electric stoves in some older homes, most modern building codes require ventilation for gas stoves to remove carbon monoxide.
3. What is better: Ducted or Ductless?
Ducted is always better because it removes heat and humidity entirely from the house. Ductless is a good alternative only when venting outside is impossible.
4. How high should a range hood be installed?
The standard height is between 28 and 32 inches above the cooktop surface. Installing it too high reduces efficiency; too low is a safety hazard.
5. What is CFM?
CFM stands for Cubic Feet per Minute. It measures the airflow capacity of the fan. Higher CFM means more suction power.
6. How do I clean my range hood filters?
Metal baffle or mesh filters can be soaked in hot water with baking soda and dish soap, or placed in the dishwasher. Charcoal filters (for ductless) cannot be cleaned and must be replaced.
7. Are range hoods loud?
All hoods make noise due to air movement. However, high-quality hoods like Brano use efficient motors that operate at under 70dB, making them unobtrusive.
8. Does the size of the hood matter?
Yes. The hood should be at least as wide as your cooktop. For better performance, professionals recommend a hood 6 inches wider than the stove.
9. What is a "convertible" range hood?
A convertible hood can be installed as either ducted (vented outside) or ductless (recirculating) by adding charcoal filters. Most Brano hoods are convertible.
10. How much does a good range hood cost?
Prices vary by style and power. A quality wall mount hood typically ranges from $200 to $800, while custom insert or island hoods can range from $400 to $1,500.
